![]() ![]() The main upside of acoustic foam is that it’s easy to install. They are however more convenient then pure MLV because they’re self-adhesive and easier to install. This is why all of those sound deadening mats such as Dynamat and Noico (affiliate linke) contain similar ingredients to MLV. Road noise and engine noise is effectively high impact noise, and acoustic foam stands no chance against it. When it comes to soundproofing vehicles, mass loaded vinyl is the clear winner. ![]() In comparison, acoustic foam is placed on the wall surface (externally), so it only acts as a superficial barrier, similarly to noise-reducing curtains hung on the window instead of installing soundproof glass. This provides it with an opportunity to structurally improve the sound insulation of the wall. This is the main point of separation between MLV and acoustic foam.Īnother important point is that MLV is typically installed inside the wall (on the studs). The impact noise can be caused by a drill or a vibrating appliance (for example a washer). For example, airborne sound is the sound of talking or a loud TV set. Because it’s such a dense and strong material, MLV works great for blocking both airborne and impact noise.Īirborne sounds are those transmitted through air, while impact are the ones that are caused by vibrations to a surface. It was first used by NASA and later got sold on the wider market for more “earthly” soundproofing projects. Mass Loaded Vinyl (MLV) has been used as a sound barrier since the 1960s. Effectiveness against airborne and impact noise Here are 10 important things to keep in mind: 1. If used as a sound barrier, acoustic foam will only protect against lower airborne noise. Acoustic foam is not dense and heavy enough to cancel vibration noise. MLV is the better than acoustic foam for blocking impact/vibration noise. However, both materials have positive and negative attributes and they should be used in specific circumstances to obtain the best result. They’re quite affordable and can be used in simple DIY soundproofing projects.

Mass Loaded Vinyl Noise Barrier provides reduced noise transmission through ceilings, walls, floors, machinery enclosures and ductwork.Īuditoriums, conference and board rooms, hotels, medical facilities, retail stores, theaters, schools, audiophile rooms, lobbies, recording studios, houses of worship, manufacturing and industrial facilities, music practice and band rooms, airports, apartments, condos and more. MLV is available in a non-reinforced version for wall and ceiling installations and a reinforced version for installations that require hanging or mounting with grommets. It is commonly used in new construction and also to correct noise problems in existing spaces. When noise and sound transmission needs to be effectively controlled, Mass Loaded Vinyl (MLV) Noise Barrier is one of the components in building noise barriers and soundproof walls.
